The first thing that's broken is that the "sType" field isn't
VK_STRUCTURE_TYPE_PIPELINE_SHADER_STAGE_CREATE_INFO, but we're also
passing invalid "module" handles.
If in the same shader_test file we have both a [buffer uav n] and a
[uav n] with the same slot "n", we want the last one to override the
first one instead of passing both resources to the backends.
Same for [buffer srv n] and [texture n] after we introduce SRV buffers.
At the current moment this is a little odd because for SM1 [test]
directives are skipped, and the [shader] directives are not executed by
the shader_runner_vulkan.c:compile_shader() but by the general
shader_runner.c:compile_shader(). So in principle it is a little weird
that we go through the vulkan runner.
But fret not, because in the future we plan to make the parser agnostic
to the language of the tests, so we will get rid of the general
shader_runner.c:compile_shader() function and instead call a
runner->compile_shader() function, defined for each runner. Granted,
most of these may call a generic implementation that uses native
compiler in Windows, and vkd3d-shader on Linux, but it would be more
conceptually correct.
If the runners require multiple calls to run_shader_tests() for
different shader model ranges, these are moved inside the sole runner
call.
For the same reason, the trace() messages are also moved inside the
runner calls.
